The Wacker Neuson is a genuine OEM Cotter Pin designed for a wide range of Wacker Neuson trash pumps and vibratory plate compactors, including PTS4V, PTS4V(I), PT2A, PT2B, PT2Y, PT3A, PT3B, VPG165V, VPG165A, and VPG170A series machines, as well as the CUB300HD indirect-fired air heater. As a genuine OEM part, the is sourced directly through Wacker Neuson's authorized supply chain, ensuring it meets the exact material grade and dimensional specifications called out in the original equipment design. Cotter pins are a critical retention fastener — the right fit matters, and using the verified OEM part eliminates the guesswork on cross-compatibility across this broad range of equipment families.
Key Features
- OEM-Specified Material and Dimensions — Manufactured to the exact diameter, leg length, and material grade specified by Wacker Neuson, ensuring correct retention force without over-stressing the mating fastener or shaft.
- Single Part Number, Broad Coverage — One genuine OEM part serves PTS4V and PTS4V(I) trash pumps, PT2 and PT3 series centrifugal trash pumps, VPG165V, VPG165A, and VPG170A vibratory plates, and the CUB300HD air heater.
- Drop-In Retention Fastener — Installs through an existing castle nut, clevis pin, or shaft bore without any modification — spread the legs after insertion and the fastener is locked.
- Prevents Unintended Fastener Backing Out — A correctly installed cotter pin locks castle nuts, clevis pins, and axle pins in place; a missing or deformed pin can allow critical connections to work loose under vibration and load.
- Safety-Critical Retention Role — On vibrating and rotating equipment like plate compactors and centrifugal pumps, cotter pin failure can result in mechanical disconnection of load-bearing or drive components — always replace with the correct OEM specification part.
A cotter pin is a small but mechanically essential fastener used to lock castle nuts, clevis pins, pivot pins, and axle shafts in position, preventing them from backing out or rotating free under vibration, load cycling, or torque. On high-vibration equipment such as vibratory plate compactors and centrifugal trash pumps, repeated mechanical shock places constant stress on every fastener in the drivetrain and pump assembly — a missing or fatigued cotter pin in those locations allows connected components to shift, wear unevenly, or separate entirely. Replacing a worn or single-use cotter pin with the correct OEM part at every service interval is a straightforward step that protects the integrity of the larger assembly it secures.
